Hydrogen gas can be prepared by reacting metallic sodium with water: 2Na (s) + 2H2O (l) → H2 (g) + 2NaOH (aq). If the price of sodium were 165/kg, what would be the cost of producing 1.00 mol of hydrogen. Ignore the cost of the water.

Answer: cost of Na = 7.59

Explanation:

From the given balanced equation, 2 mol Na/2x23 g produced 1 mol of H2 gas

And cost of Na is 165 for per Kg or 1000 g Na

Then cost of Na for 2x23=46 g Na

Cost = 46x165/1000 = 7.59
